Abstract: This article presents an optimized hybrid one-step block method for the direct numerical integration of second-order initial value problems (IVPs) of the form y′′ = f (x,y,y′). The method is derived using a power series basis function through Read more

Abstract: The aim of this article is to introduce the notion of F-metric spaces and establish some fixed point results for relation-theoretic contractive type mapping in a complete F-metric space. These contributions extend the existing literature on relation-theor Read more

Abstract: In numerous developing nations, traditional medicine is one of the basics of health care due to limited access to conventional medical systems. Mangifera indica (Linn.) is an indigenous treatment for managing chronic illnesses. However, little quantitativ Read more

Abstract: In (Mediterr. J. Math. 11, 703–711, 2014), Shukla introduced the concept of partial b-metric spaces as a generalization of partial metric and b-metric spaces. The purpose of this article is to establish some coupled fixed point results for contracti Read more

Abstract: This study evaluates the effects of overloading on the operational performance, efficiency, and lifespan of 11 kV distribution transformers using ten transformer substations in Ile-Oluji, Ondo State, Nigeria, as case study. Field measurements of load currents, Read more
